- To evaluate whether C-reactive protein (CRP), including variation within the normal range, is predictive of long-term disease outcome in Juvenile Idiopathic Arthritis (JIA). Consecutive patients with newly diagnosed JIA were included prospectively from defined geographic areas of the Nordic countries from 1997 to 2000. Inclusion criteria were availability of a baseline serum sample within 12 months after disease onset and 8-year clinical assessment data. Systemic onset JIA was not included. CRP was measured by high-sensitive ELISA (detection limit of 0.2 mg/l). One hundred and thirty participants with a median follow-up time of 97 months (range 95-100) were included. At follow-up, 38% of the patients were in remission off medication. Absence of remission was associated with elevated level of CRP at baseline (odds ratio (OR) 1.33, confidence interval (CI) 1.08-1.63, p = 0.007). By applying a cutoff at the normal upper limit (> 10 mg/l), the risk of not achieving remission was increased to an OR of 8.60 (CI 2.98-24.81, p < 0.001). Variations of CRP within the normal range had no predictive impact on disease activity at follow-up. Baseline levels of ESR were available in 80 patients (61%) and elevated ESR was associated with absence of remission in a multivariable logistic regression analysis (OR 2.32, CI 1.35-4.00, p = 0.002). This results of this study indicate that baseline CRP concentrations above 10 mg/l are predictive of a poor outcome at 8-year follow-up. We could not demonstrate any predictive value of CRP variations within the normal range.

- To test the hypothesis that non-HLA single-nucleotide polymorphisms (SNPs) associated with the risk of juvenile idiopathic arthritis (JIA) are risk factors for an unfavourable disease outcome at long-term follow-up.The Nordic JIA cohort is a prospective multicentre study cohort of patients from the Nordic countries. In all, 193 patients met the inclusion criteria of having an 8year follow-up assessment and available DNA sample. Seventeen SNPs met the inclusion criteria of having significant associations with JIA in at least two previous independent study cohorts. Clinical endpoints were disease remission, actively inflamed joints and joints with limitation of motion (LOM), articular or extra-articular damage, and history of uveitis.Evidence of associations between genotypes and endpoints were found for STAT4, ADAD1-IL2-IL21, PTPN2, and VTCN1 (p=0.003-0.05). STAT4_rs7574865 TT was associated with the presence of actively inflamed joints [odds ratio (OR) 20.6, 95% confidence interval (CI) 2.2->100, p=0.003] and extra-articular damage (OR 7.9, 95% CI 1-56.6, p=0.057). ADAD1_rs17388568 AA was associated with a lower risk of having joints with LOM (OR 0.1, 95% CI 0-0.55, p=0.016). PTPN2_rs1893217 CC was associated with a lower risk of having joints with LOM (OR 0.2, 95% CI 0-0.99, p=0.026), while VTCN1_rs2358820 GA was associated with uveitis (OR 3.5, 95% CI 1-12.1, p=0.029).This exploratory study, using a prospectively followed JIA cohort, found significant associations between long-term outcome and SNPs, all previously associated with development of JIA and involved in immune regulation and signal transduction in immune cells.

- A large proportion of patients with mutations in the Wiskott-Aldrich syndrome (WAS) protein gene exhibit the milder phenotype termed X-linked thrombocytopenia (XLT). Whereas stem cell transplantation at an early age is the treatment of choice for patients with WAS, therapeutic options for patients with XLT are controversial. In a retrospective multicenter study we defined the clinical phenotype of XLT and determined the probability of severe disease-related complications in patients older than 2 years with documented WAS gene mutations and mild-to-moderate eczema or mild, infrequent infections. Enrolled were 173 patients (median age, 11.5 years) from 12 countries spanning 2830 patient-years. Serious bleeding episodes occurred in 13.9%, life-threatening infections in 6.9%, autoimmunity in 12.1%, and malignancy in 5.2% of patients. Overall and event-free survival probabilities were not significantly influenced by the type of mutation or intravenous immunoglobulin or antibiotic prophylaxis. Splenectomy resulted in increased risk of severe infections. This analysis of the clinical outcome and molecular basis of patients with XLT shows excellent long-term survival but also a high probability of severe disease-related complications. These observations will allow better decision making when considering treatment options for individual patients with XLT.

Tidskriftsartikel (refereegranskat)abstract
- Background: selective IgA deficiency is the most frequent primary immunodeficiency worldwide. Patients are usually asymptomatic. However, those cases with symptoms develop recurrent infections and increased risk of autoimmune and malignant diseases. On the other hand, rheumatic disorders are uncommon during childhood with juvenile idiopathic arthritis as the most common one. Case Presentation: we present the case of a female patient, who developed oligoarticular juvenile idiopathic arthritis at age 7 years. After the diagnosis, she developed acute anterior uveitis. During the initial immunological evaluation, the diagnosis of selective IgA deficiency was confirmed. A work-up for immunodeficiency demonstrated a normal T cell compartment. B cell subpopulations showed normal memory B lymphocytes, absence of transitional B cells, and an increase in the CD21 low unique subset. Conclusions: at the beginning of any rheumatological evaluation, the physician should request immunoglobulins levels, in order to detect possible primary antibodies deficiencies.

Tidskriftsartikel (refereegranskat)abstract
- Previous epidemiological studies of juvenile chronic arthritis (JCA) report divergent results owing to differences in diagnostic criteria, patient retrieval, and study designs. To investigate incidence and prevalence of JCA in a total population, this prospective survey was performed in southwestern Sweden between 1984 and 1988. Cases were identified using the European League Against Rheumatism criteria for JCA and were reported annually from eight pediatric departments and local pediatricians in the studied area. During the 5 years, 213 new cases of JCA were found, corresponding to an incidence of 54.6 per 100,000 children younger than 16 years of age. The average annual incidence was 10.9 per 100,000. The peak incidence rate, 18.3 per 100,000 was found in girls 0 through 3 years old. The lowest incidence rate, 6.4 per 100,000, was found among boys 12 through 15 years old. In December 1988, 334 cases of JCA were recorded, giving a prevalence of 86.3 per 100,000. When patients in remission were omitted the prevalence was 64.1 per 100,000. The monoarticular+pauciarticular onset type constituted 68.3% of the prevalence cases, while 21.9 were polyarticular and 6.6% had systemic onset. To avoid underestimation of incidence and prevalence, and to get a correct picture of disease patterns, epidemiological surveys of JCA should be population-based rather than referral center-based. Further descriptive studies of JCA in different well-defined geographic areas are important to make valid comparisons. Such comparisons could give clues to etiological factors, both genetic and environmental.

- OBJECTIVE: To investigate the health-related quality of life (HRQOL) change over time, as measured by the Child Health Questionnaire (CHQ), and its determinants in patients with active juvenile dermatomyositis (DM). METHODS: We assessed patients with juvenile DM at both baseline and 6 months of followup, and healthy children age < or =18 years. Potential determinants of poor HRQOL included demographic data, physician's and parent's global assessments, muscle strength, functional ability as measured by the Childhood Health Assessment Questionnaire (C-HAQ), global disease activity assessments, and laboratory markers. RESULTS: A total of 272 children with juvenile DM and 2,288 healthy children were enrolled from 37 countries. The mean +/- SD CHQ physical and psychosocial summary scores were significantly lower in children with juvenile DM (33.7 +/- 11.7 versus 54.6 +/- 4.1) than in healthy children (45.1 +/- 9.0 versus 52 +/- 7.2), with physical well-being domains being the most impaired. HRQOL improved over time in responders to treatment and remained unchanged or worsened in nonresponders. Both physical and psychosocial summary scores decreased with increasing levels of disease activity, muscle strength, and parent's evaluation of the child's overall well-being. A C-HAQ score >1.6 (odds ratio [OR] 5.06, 95% confidence interval [95% CI] 2.03-12.59), child's overall well-being score >6.2 (OR 5.24, 95% CI 2.27-12.10), and to a lesser extent muscle strength and alanine aminotransferase level were the strongest determinants of poor physical well-being at baseline. Baseline disability and longer disease duration were the major determinants for poor physical well-being at followup. CONCLUSION: We found that patients with juvenile DM have a significant impairment in their HRQOL compared with healthy peers, particularly in the physical domain. Physical well-being was mostly affected by the level of functional impairment.

- Objective To study self-reported pain early in the disease course of juvenile idiopathic arthritis (JIA) as a predictor of long-term disease outcomes. Methods Consecutive cases of JIA with disease onset from 1997 to 2000 from defined geographical areas of Norway, Sweden, Finland, and Denmark were prospectively enrolled in this population-based cohort study. Self-reported, disease-related pain was measured on a 10-cm visual analog scale (VAS pain). Inclusion criteria were a baseline visit with a pain score 6 months after disease onset, followed by an 8-year study visit. Remission was defined according to Wallace et al (2004) preliminary criteria. Functional disability was measured by the Childhood Health Assessment Questionnaire and the Child Health Questionnaire Parent Form if the child was age <18 years and by the Health Assessment Questionnaire if age >= 18 years. Damage was scored using the Juvenile Arthritis Damage Index. Results The final study cohort consisted of 243 participants, and 120 participants (49%) had oligoarticular onset. At baseline, 76% reported a VAS pain score >0 compared to 57% reporting at 8 years. Half of those who reported baseline pain also reported pain at 8 years but at a lower intensity. Compared to no pain, higher pain intensity at baseline predicted more pain at 8 years, more functional disability, more damage, and less remission without medication. Baseline pain predicted more use of disease-modifying antirheumatic drugs/biologics during the disease course. Participants with oligoarticular JIA reporting pain at baseline were more likely to develop extended oligoarticular JIA or other JIA categories with an unfavorable prognosis. Conclusion Early self-reported, disease-related pain among children and adolescents with JIA is common and seems to predict persistent pain and unfavorable long-term disease outcomes.
